Artists with other commonly accepted names will be accepted (e.g. Leonardo AND Da Vinci) would be accepted - (the mosaics are unattributed so the artist name is just "mosaic")
"The" will generally not matter - If your answer is not accepting and you have typed "the", try removing it
Punctuation does not matter
Some names of pieces (especially older ones) have multiple generally accepted names, any of them should be accepted but I have to put all of these in manually so not all possible names may be acceptable
